@odessitka,
Yes, go see a lawyer.
As for not telling your sister-in-law that you don't want your brother-in-law to live with you so she doesn't think that you don't want him there—er, do you even hear yourself?
You
don't want him there. Pretending that you do isn't going to do you any good. So, if you have to tank the relationship with your sister-in-law, then so be it.
You need to protect yourself and your girls. Period, end of story. Your sister-in-law becoming offended is the least of your concerns.
I'm actually a lot more troubled by your husband's attitude. He's ready to give his brother a free pass on assaults because it was a long time ago and the guy was drunk.
Those. Are. Not. Good. Enough. Explanations.
They are excuses, and they are exceedingly lame ones.
But let's say for sake of argument that your husband is right, it was a long time ago and the guy was drinking and it was an anomaly.
So, what, exactly, does your husband expect his brother will do all day long, stuck in the house, not knowing English and not working? I have to doubt that there are many Ukrainian speakers in your area. Probably not too many library books in Ukrainian, either.
I enjoy online stuff as much as the next person, but it only goes so far. And this is even getting an online degree, but from the sounds of it, I doubt the guy will be ambitious enough to do that without some massive prompting.
With no English skills, food shopping is probably out of the question. Driving would be problematic at best, and that's assuming he could get a license in the US in the first place.
What sorts of activities is he left with? Here are the only ones I could come up with:
- Cooking and cleaning
- Drinking
- Doing drugs
- Masturbating
- Breaking the law in some way or another
- Bothering you or your kids or both
- Having an affair
- Writing a book or otherwise making art (if he's shown no inclinations in this area, then he's not about to start)
- Volunteering (which will likely require English language skills and will certainly smell a lot like work
- Working out
Most of these are not productive uses of his time.
And if anyone thinks that he is going to magically become responsible and get a good job in the US or Canada after 1 1/2 - 2 years of being idle, I have a bridge to sell that person.
In the absolute
best possible scenario, the guy will be bored out of his mind, end up being able to run a marathon, keep an immaculate house, make enough art for an art show, run a soup kitchen, and learn how to cook.
If 1/10 of any of those things does not sound even remotely possible (and I bet that's the case), then this scenario just leaves the guy with no social support system, no skills, no responsibilities, and no accountability.
My advice.
Talk to a lawyer, but also talk to your husband. But don't frame it in terms of your own discomfort or your worry for your daughters, as he's (unfairly, and disturbingly) dismissed that already.
Talk to your husband about his brother being bored, and losing his skills. About how if his brother doesn't learn English, he is committing himself and his wife to a life of poverty at best. About how his brother will be wasting a few years of his life.
Insist that your brother-in-law be enrolled in English classes and going to class. Insist that your brother-in-law be working or at least actively looking for work. And if he doesn't know English, then I've got news for him: any sort of interesting positions are utterly off the table. He'd likely be washing dishes or the like.
Insist that your husband lay down these laws to your brother-in-law.
And if your husband refuses, or your brother-in-law doesn't hold up his end of things?
Then take your girls and leave.
